The blonde beauty started dating the Swiss businessman after meeting at the Cannes Film Festival last May, and was rumoured to have relocated to Europe to be close to him.

MailOnline has contacted Paris' representative for comment.

News of the split is likely to come as a shock since Paris previously confessed she had finally found The One.

'Thomas is my soulmate. I've never been happier. He doesn't like fame, he just wants me', she told Closer magazine.

'With my previous boyfriends, I felt there was always an intention, but with him I know it's all about love.'

The relationship seemed more serious than others - the beauty has also dated River Viiperi and Cy Waits.

Paris told DailyMail.com in October she was spending a 'nice, romantic' with Thomas over Christmas.

'We're going to have a nice, romantic holiday.'
